I have seen an Impreza STi (Type UK 2004/05) fuel pump for sale. Would this be an upgrade for a MY99 UK? Anyone know what the flow rate is?

I have about 270 - 280 bhp potential and it looks a bit weak at the top end.

 

Apparently, according to the seller it is 35 gallons/hour which is about 160 litres/hour. Not enough to warrant changing from a standard classic UK 99 do you think?

 

hope its cheap as they get changed when fitting ppp kit and usually get thrown in the bin so not worth a lot

 

Yes, £20 'buy it now' on ebay. Won't bother.
